For high end professional services like dental and legal … those are some of the best geo-local keywords to go after because the traffic value is so high per click. Even a few dozen visitors a week to a website (when combined with a conversion focused website) can generate a few leads worth $100+ each and every week.

And I would say “Miami restaurant” is a pretty crappy keyword to target with general SEO services. When I look at Google’s search results I see the map with 7 listings, then links to search results for 5 categories of restaurants, then 5 more links for “restaurants near x” … so that means that there are 17 links *before* any organic search results. Further the keyword is a general discovery and comparison keyword…not one with highly targeted intent, so even if you do rank well then odds are your user experience won’t likely be seen anywhere near as relevant to end users as Yelp, Fodors, TripAdvisor, CitySearch, etc.

And this experience is not only played out / proven by the current set of organic search results, but also if you look at the paid ads on that keyword you see more general aggregators … Bing, Groupon, and Pronto. There are only 2 ads for restaurants out of 8 (and even one of the ads is for appartments).
